My Daily Supplement Routine for Steady Glucose and Better Health

Video transcription : My Daily Supplement Routine for Steady Glucose and Better Health

In my book, compared to what I’m about to tell you in a second, I just don’t think it’s the best supplement to take for your glucose levels. To me, it’s not enough effect, there are a lot of drawbacks, and it’s way too many pills. I don’t want to take eight pills a day, so I’m just like, no.

Hello angels and welcome back to the Glucose Goddess Show. My name is Jessie Inchauspé. I’m a French biochemist obsessed with helping you understand your body and your health, and most of my work centers around glucose levels — blood sugar levels.

Over the years, I’ve discovered that glucose spikes can lead to many symptoms and that keeping our glucose levels nice and steady is the foundation of physical and mental health. So today I want to walk you through the science of natural supplements that can — or maybe cannot — help us with our glucose levels. I’m going to show you all the supplements I do not take and why I’ve decided not to take them based on the science, and then I’ll show you the specific supplement stack or formula that I’ve designed and that I take every single day to help my glucose levels. If I could only take one of these supplements for the rest of my life, I’ll show you which one that is. So let’s get into it.

We’re going to go through a few plant molecules that I’ve added to my routine, but before that, I want to talk to you about the things that I do not take and why. One of my core glucose hacks is to have vinegar before eating food, because just a tablespoon of regular vinegar can significantly cut the glucose spike of a meal. Unfortunately, vinegar capsules do not work. A study called “A Comparison of Liquid Vinegar and Commercial Vinegar Pills for Managing Insulin Resistance and Postprandial Glucose Concentrations” showed that while liquid vinegar works, the capsule form does not. It even seemed to make insulin resistance worse when liquid vinegar made it better. This is the main good study we have; it’s not a lot, but the evidence isn’t sufficient to say that vinegar capsules can have the same effect as regular vinegar. So I do not take or recommend vinegar capsules, because the little evidence we do have points to them not working. The vinegar hack only works with regular vinegar. Always dilute it in water before you drink it, or use it on your veggie starter. Second, vinegar gummies — no, don’t take them. Vinegar gummies contain sugar. The popular red ones everyone takes are full of sugar. Not only do we lack evidence that vinegar in non-liquid form works, but these gummies have added sugar that worsens your glucose levels. They’re pure marketing and do not work. For example, a slice of bread on its own versus with vinegar gummies shows no difference — even a slight increase in the glucose spike, which isn’t surprising given that one or two gummies contain about one gram of sugar each. So vinegar capsules and vinegar gummies: best case, they don’t work; worst case, they’re harmful.

Next, fiber pills. One of my hacks is to eat veggies first at a meal — the fiber creates a protective mesh in your intestine, slowing glucose absorption. People often ask if they can just take fiber pills instead. Technically you could, but you’d need a lot to equal a cup of broccoli. For instance, you’d need six psyllium husk capsules before a meal to match one cup of broccoli. If you want to take six capsules of fiber before every meal, up to you — they likely won’t hurt, though they can cause bloating or gas — but it’s not worth it: too many capsules, minimal effect. Next supplement: bitter melon. It’s popular, but a systematic review and meta-analysis called “Effect of Bitter Melon in Patients with Diabetes” found that supplementing for 4 to 12 weeks did not significantly lower HbA1c or blood sugar in people with type 2 diabetes compared to placebo. Another review, “Effectiveness and Safety of Ayurvedic Medicines in Type 2 Diabetes,” found a small improvement — bitter melon reduced HbA1c by 0.3%. That’s minimal. In my opinion, not enough to justify taking it daily. Next: berberine.

Also very popular for glucose. A review called “Efficacy and Safety of Berberine Alone for Several Metabolic Disorders” found that after two months of taking two grams of berberine daily — about eight to ten pills — fasting glucose improved. So berberine works, and it’s cheap, but it has drawbacks. First, you need to take many pills daily (about eight), which is a lot. Second, you have to wait two months to see results — it’s a long game. Third, it has no impact on the glucose spike from a meal — it doesn’t help with immediate spikes, which is what I care about most. And fourth, high doses may cause side effects; agencies like ANSES and EFSA haven’t declared high-dose long-term use completely safe yet and recommend caution. So even though berberine has a good reputation, to me it’s not the best supplement for glucose control — not enough effect, too many pills, too slow.

Now, time to tell you about the two amazing plant molecules that I discovered during this research that I take every single day. The first is mulberry leaf extract — from the leaves of the beautiful mulberry tree — which contains a molecule called DNJ. DNJ interacts with enzymes in your stomach and intestines called alpha-glucosidase, whose job is to break down starches into glucose. DNJ tells those enzymes to “chill out,” slowing how fast starches turn into glucose. This means glucose enters your bloodstream more slowly, reducing the spike — just like my glucose hacks do. With the proper dose of DNJ before a meal, you can cut the glucose absorption of that meal by up to 40%. It doesn’t touch proteins, fats, vitamins, or minerals — only starches and sugars (maltose, sucrose, fructose, lactose).

A study called “Mulberry Leaf Extract Improves Glycemic Response and Insulinemic Response to Sucrose in Healthy Subjects” found that 250 mg of mulberry leaf extract — the clinical dose — reduced both glucose and insulin spikes by up to 40%. This is important because it means glucose drops without causing excess insulin, which can have negative effects. For example, eating a bagel with versus without 250 mg of mulberry leaf extract shows a clear reduction in glucose spike. This molecule is incredibly powerful, much stronger than vinegar, and nothing else provides such immediate effect on meal spikes. Reducing spikes reduces cravings (smaller dips mean fewer urges to eat sugar), improves energy, and reduces inflammation and fatigue. Long term, daily use improves fasting blood glucose, HbA1c, and fasting insulin levels — as shown by the same meta-analysis — an 8 mg/dL reduction in fasting glucose, almost 3 mmol/mol reduction in HbA1c, and a 0.58 µIU/mL drop in fasting insulin. Because of this, mulberry leaf extract is the number one supplement I take every day. It’s one of the two main hero molecules in my supplement, Anti-Spike Formula, which I formulated myself. Each daily dose contains 250 mg of high-quality mulberry leaf extract — the clinical dose shown to work. Anything less won’t work. A common question is, can you just have mulberry leaf tea instead? You can, but a cup of tea won’t provide enough DNJ for the clinical effect. The second plant molecule I take daily comes from lemons — it’s the molecule that makes lemons yellow, called eriocitrin. Eriocitrin acts on the L-cells lining your gut, which sense when you eat and produce a substance called GLP-1, a natural hormone that regulates appetite and glucose. Supplementing with 200 mg of eriocitrin for 3 months increases GLP-1 production by up to 17%. That means fewer cravings, better appetite regulation, and healthier glucose levels, because GLP-1 helps store excess glucose properly. In one randomized controlled study of 100 people with pre-diabetes, 200 mg daily of this lemon molecule reversed pre-diabetes in 24% of participants — fasting glucose dropped from pre-diabetic to healthy range. You can’t get enough eriocitrin from lemon juice — you’d need to drink two liters a day — so supplementation is the only way to reach the clinical dose. This combination of mulberry leaf extract and eriocitrin is, to me, the ultimate duo for both immediate and long-term glucose health. It’s what I take daily — nothing else — and it’s what’s in Anti-Spike Formula: 250 mg of mulberry leaf extract and 250 mg of lemon extract per two capsules a day. Very powerful molecules that work fast on cravings, hunger, energy, bloating, and long-term fasting glucose. I also added a high-potency cinnamon extract equivalent to one gram of cinnamon, which has its own glucose benefits, plus a blend of veggie antioxidants for extra cellular protection. This formula is the only supplement I take every day.

If you want to complement the food hacks I teach (linked in the description — my 10 glucose hacks), this is the only supplement you’ll ever need: two capsules a day, amazing short- and long-term benefits. It gives more powerful long-term results than berberine with far fewer capsules, and immediate reduction in meal spikes. When I first found this science, I got so excited. I’ve never liked taking lots of pills; I’ve always been food-first, and you should be too. But if you want a supplement to help you — if the food hacks are too hard or you want faster results — this is for you.

So, in conclusion, now you know the supplements I take every day: just two capsules of Anti-Spike before my biggest meal. I don’t take bitter melon, berberine, or vinegar capsules because they’re not the most effective. The most powerful are mulberry leaf extract and the lemon polyphenol — together they’re a super-couple.

Anti-Spike has helped me personally with bloating, staying full longer, and completely eliminating random sugar cravings. It’s been a super powerful ally, and I’m really proud of it. I hope you get to try it and love it too, because it’s truly amazing.

To close off this episode, I’ll leave you with testimonials from people in the community who’ve tried Anti-Spike. If you want to see thousands more, go to anti-spike.com or click the link in the episode description to see the science, clinical trials, and real reviews.

Thank you for watching — I’ll see you next time. This amazing formula is the real deal. Anti-Spike has truly changed my life for the better: I no longer have sugar cravings, I have fewer mood swings, I don’t feel hungry every two hours, my bloating is gone, my sleep is better, and it’s become a great part of my daily routine — from 8.0 to 5.2 with Anti-Spike.

When it comes to blood sugar, not all supplements are created equal. 

Many popular options claim to help balance glucose levels. But do they actually work?

 

I’ll walk you through the science-backed reasons why I don’t take certain common supplements, and introduce you to the two natural plant molecules I do take every single day to support my glucose levels, reduce spikes, and feel my best.

Why managing glucose spikes is so important

Glucose spikes (those sharp rises in blood sugar after a meal) can lead to short-term symptoms like cravings, fatigue, brain fog, and even long-term health issues like inflammation, hormone imbalance, prediabetes, diabetes and heart disease. That’s why keeping glucose levels steady is one of the most effective things we can do for our physical and mental well-being.

I always say: food comes first. My 10 Glucose Hacks are the foundation.

But if you're looking for an extra layer of support from supplements, here's what works, and what doesn’t.

Popular glucose supplements I don’t take (and why)

1. Vinegar capsules & vinegar gummies

While a tablespoon of liquid vinegar before meals can reduce glucose spikes by up to 30%, vinegar capsules and gummies don’t seem to work.

A study comparing the liquid and capsule forms found that vinegar capsules did not have a significant effect on glucose spikes and did not improve insulin resistance. On the contrary, the capsules may even worsen it. (read study)

What about vinegar gummies? They often contain added sugar, which defeats the purpose entirely.

Verdict: Liquid vinegar works. Capsules and gummies are not worth it.

2. Fiber Pills

Fiber is amazing for glucose control when it comes from whole foods like vegetables. So theoretically yes fiber pills could reduce the glucose spike of a meal. But in reality:

  • You would need 6 to 10 fiber pills before meals to blunt the glucose spike. For example, you’d need 6 capsules of psyllium husk before a meal to get the same amount of fiber as in 1 cup of broccoli. 

  • They’re often impractical, and may cause bloating or discomfort.

Verdict: Whole veggies are better. Pills are inefficient and can lead to digestive discomfort.

3. Bitter melon

Despite its popularity, studies on bitter melon show minimal effects on blood sugar levels.

  • One meta-analysis showed no significant improvement in HbA1C or fasting glucose. (ready study)

  • Another found a drop of only 0.3% in HbA1C, really not enough to justify daily use. (read study)

Verdict: Slight benefits, but not powerful enough for daily use.

4. Berberine

Berberine is well-known for its blood sugar-lowering effects. Here’s how it works:

  • There is a molecule in our cells called AMPK. Its job is to sense when your cells are running low on energy, and it tells your body to burn more glucose to make energy. 

  • Supplementing with berberine activates this AMPK molecule, which leads to more consumption of glucose.

  • The result: Your body starts using up more glucose. After supplementing daily with berberine for 2 months, studies show a lowering of fasting glucose levels and reduced insulin resistance (read study).
berberine supplement

The advantages of berberine are that it’s cheap and it works: it’s proven to reduce fasting glucose levels and insulin resistance after 2 months at a dose of 2 grams daily.

The drawbacks of berberine:

  • You have to take high daily doses (about 2 grams per day, so 5 to 8 pills per day).

  • You have to be very patient to see an effect. Only after 2 months of 2 grams daily will you notice anything.

  • It has no impact on your meals’ glucose spikes.

  • The high dose required could potentially cause side effects. Whether it’s completely safe is still debated among health agencies (ANSES, EFSA).

Verdict: Works, but inconvenient and slow. There’s a better option.

The two natural molecules I do take every day

After years of research, I found two plant molecules that truly work. They’re both backed by high-quality clinical studies, they have immediate and long-term effects, and they’ve made a noticeable difference in how I feel after meals: fewer cravings, better energy, and steadier glucose levels.

These two molecules are:

  • DNJ from mulberry leaf extract

  • Eriocitrin from lemon peel extract

Let’s dive into the science behind each one.

1. Mulberry leaf extract: reduces glucose spikes by up to 40%

Mulberry leaf extract comes from the leaves of the mulberry tree and contains a powerful compound called DNJ (1-deoxynojirimycin). DNJ inhibits an enzyme called alpha-glucosidase, which is responsible for breaking down carbs into glucose in your digestive system.

What happens when DNJ slows this process down?

  • You absorb carbs more slowly.

  • You get a flatter glucose curve after eating.

  • You avoid the cycle of glucose spike → insulin spike → energy crash.

A randomized double-blind placebo-controlled study tested 250 mg of mulberry leaf extract before a meal and found a 40% reduction in the post-meal glucose and insulin spikes (read study).

That’s a dramatic result, not only for blood sugar but also for reducing cravings and energy dips after eating.

Blood sugar supplement

Another study, a systematic review and meta-analysis of 12 randomized controlled trials with over 600 participants (read study), showed that daily use of mulberry leaf extract led to:

  • A significant drop in fasting glucose

  • A reduction in HbA1c (a marker of long-term glucose control)

  • A measurable improvement in fasting insulin sensitivity

Why I take it: It works immediately when taken before meals and also supports better metabolic health over time. I take 250 mg of high-quality extract right before my highest-carb meal each day.

2. Lemon Polyphenol (Eriocitrin): Boosts GLP-1 and Regulates Blood Sugar

The second molecule I take is eriocitrin, a natural polyphenol found in lemon peel. It’s what gives lemons their vibrant yellow color, and it does much more than that.

Eriocitrin has been shown to increase the body’s production of GLP-1, a hormone secreted by your gut when you eat. GLP-1 plays a vital role in:

  • Reducing appetite

  • Slowing gastric emptying

  • Enhancing insulin secretion

  • Improving blood sugar reduction

In a recent crossover randomized clinical trial, participants who took 200 mg of eriocitrin daily for 3 months had a 22% increase in GLP-1 production (read study).

But perhaps the most exciting finding came from a study on people with prediabetes: 24% of participants reversed their condition entirely (meaning their fasting glucose dropped back to healthy levels) after just 3 months of eriocitrin supplementation (read study).

Eriocitrin also has anti-inflammatory and antioxidant properties, which further support overall metabolic health.

Why I take it: It acts via a completely different pathway from mulberry leaf, and it supports long-term glucose control, appetite regulation, and even fat metabolism. It’s a perfect complement to DNJ.

Anti-Spike Formula: my daily glucose supplement

I didn’t start out as someone who wanted to create a supplement. Honestly, I’ve always leaned food-first, and minimal when it comes to pills. But when I started seeing the evidence for DNJ from mulberry leaf and eriocitrin from lemon extract, I got really excited.

This wasn’t marketing. This was data. Multiple randomized controlled trials, meta-analyses, dose-specific results — all pointing to real, measurable effects on blood sugar.

I tested both of these ingredients individually. I noticed a drop in my post-meal spikes. I felt fewer cravings. My energy stayed more stable. My "sugar crashes" were basically gone.

So I asked myself: What if we combined these molecules? At the exact doses used in clinical trials? What if we created a formula that:

  • Works immediately: reduces the glucose spike of the very next meal.

  • Supports long-term health: improves fasting glucose, insulin sensitivity, and cravings over time.

  • Is natural, safe, and low-effort: just a couple of capsules a day.

  • And most importantly: is scientifically backed at the right clinical doses, not under-dosed or hype-driven.

And so that’s exactly what I built.

Blood sugar supplements

What's inside Anti-Spike?

  • 250 mg Mulberry Leaf Extract (DNJ)
    The same dose used in trials showing up to 40% reductions in post-meal glucose spikes (read study), and improved long-term fasting glucose and HbA1c (read study).

  • 250 mg Lemon Extract (Eriocitrin)
    Shown to increase GLP-1 levels by 22% (read study), support appetite regulation, and even reverse prediabetes in 24% of cases (read study).

  • Cinnamon Extract (1 g equivalent)
    A highly potent extract of ceylon cinnamon, another plant with tons of evidence supporting its effect on fasting glucose over time (read study).

  • Veggie Antioxidants
    To boost cellular health, support inflammation balance, and reflect the antioxidant power of the glucose hacks I teach.

How I Use Anti-Spike

I take two capsules a day, just before the meal that’s highest in carbs, which is often dinner. The effect is real: I don’t get that big spike → crash cycle anymore. I feel full for longer. And I’ve completely lost the urge to snack on sugar afterward, even when it’s around.

I still do my glucose hacks (like having a savoury breakfast, eating veggies first, moving after eating), but Anti-Spike gives me an extra layer of protection, and just makes life so much easier when I’m busy, traveling, or eating something I can’t fully control.
